• STRi (Formerly TR1) Adjustable seat runner set

The TR1 adjustable seat runner set is double locking for safety and they allow 25 cm of leg length adjustment.

They can be used in conjunction with car seats B1, B2, and B4 when using the TB1 brackets. They can also be used under the TBF1 brackets when using seats B6 Screamer, B6 XL Screamer and B7 and also when fitting the B5 seat coupled with TB2 or TB3 brackets, turned under the seat creating a narrow footprint.

When using the bottom mounted B6 seat and directly mounting the TR1 runners under the seat without brackets, a special fitting kit TK5 with extra spacers is needed. For more info, click here. When the option of a side mounted B6 is taken, then the runners will need bracket sets the same as used for the B6 Screamer, B6 XL Screamer and B7.

The TR1 runners can also be bolted directly to the bottom the W1/W2 seats, but only when these seat models are fitted with the optional back frame.

Weight: 1.38 kg

Please note we strongly recommend that you do not use seat adjustment runners for race use.

Side mount brackets also needed to connect to B1, B2, B4, B5, B6 Screamer, B6 XL Screamer, B7, B8 and B9 seats
